This invention relates to improvements in base exchange water softeners.

An object of this invention is to provide means for preventing the scum and base exchange mineral fines from entering the service pipe. 7 Another object of this invention is to provide means for regulating the'flow rate, preferably in the form of a loosely positioned elllement within the saltpot connected with fAfurther object is to provide a convenient and simple method or device for adding the salt solution at the regenerating periods.

For this purpose, a filtering material in the form of a porous plate or filter screen, or any filtering provided having suitable of slidably positioning the material within the saltpot.

Another object of this invention is to provide means for placing the saltpot and filter at the side of the base exchange mineral container, thereby enabling the softened Water to pass into the saltpot in a manner allowing the scum and sediment to accumulate in the top of the saltpot and the fine exchange mineral to accumulate near the bottom of the saltpot.

One of the objects is to provide means for drawing the scum and sediment from the saltpot.

Further objects of this invention'will appear in the following detailed description of the device and as disclosed of drawings herewith made a part of this ap lication.

Similar numerals designate identical parts in the different figures of the drawings.

Numeral 1 designates the container of the ass exchange water softener holding therein the filtering layer 2, preferably of gravel, a layer of quartz 3, and a finer layer of quartz 4 orother suitable filtering material. Above this layer 4 is positioned a proper quantity of base exchange mineral 5, allowing a free-boardspace 6 between the upper portion of the container 1 and the top of the base exchange mineral 5. of the container 1 is a which the filtering material is adapted to be held in position.

Leading from'a suitable point in the container casing 1, preferably from the bottom thereof as at 8, is a connection line 9 leading to drain valve 10 and raw water supply a raw water supply valve 12, to a T 13 leading to the raw water city mains or supply. From the raw water supply T 13 is a'connecting nipple 14 leading to the bypass valve 15, the bypass valve 15 obviously being closed during the softening operation.

Over an opening suitably positioned in the base exchange water softener container 1 at the top thereof, is adapted to be placed a saltpot attachment 16. This saltpot attachment 16 may be designed to connect with the container in any suitable inannen'such as disclosed in the Figures 1, 8, 9 and 10.

Numerals 17, 18 and 19 designate parts of the saltpot attachment which may be of any suitable construction. I

ously, the stream of water is baflIed at this point and deflected toward the ends of the plate where the lowest row of holes 31 are located. V 7

At the end of the plate 7 the small jets flowing through the holes 31 est impulse caused by the reaction in the corners of the plate and head. These impulses as are readily apparent diminish toward the baffle plate center. Between the baffle plate portion 30 and the lowest row of holes 31, are other holes or openings 32 and 32 through which jets of incoming liquid will flow with decreased pressure, is indicated clearly in the diagrammatic view as disclosed in Fig. 6.

The arrangement the plate 7 practically creates a discharge at the top surface of the such a manner that the jets of water termlnate at the same level and therefore the rise of the water or flow into the filtering materials 2, 3, and 4 will be on a uniform level as clearly shown at line 33 in Fig. 6.

It is to be understood that the size and'number of holes in the perforated plate 7 have a certain relation to the influx and discharge conditions of flow. The plate 7 may or may not cover the bottom of the tank container, or it may extend over only a portion thereof.

In addition to the functions and advantages of the perforated plate 7 as described above, it may be stated that it is also adapted to support the filtering material such as gravel, quartz and mineralbed and forms with a bottom portion of the tank container 34 a precipitating chamber 35 wherein those impurities which are arrested by the plate 7 and otherwise may be accumulated for removing through any suitable means.

ture 20, located preferably in the upper porcontainer 1, the aperture 20 being of a size sufficient to enable the proper amount of filtering material such as gravel, mineral and the like to be supplied -to a' tank container 1. After the soft water leaves the free-board space 6, it enters through the aperture 20 into the salt supply nozzle 21 which is constructed in such a manner that it acts as a damper to keep all the scum, fines and the like out of the service pipe 43 by means of a porous plate or screen as at 22. The ele- -ment 22 may be of any suitable material, and ing 23 comprising any desirable shape and formed of rubber material or otherwise as disclosed at 23 and 24 in Figures 4: and 5.

It is to be understood that any suitable form of gaskets may be used in making the porous plate 22 slidably positioned ,with the minimum amount of clearance between its edges Any impurities and scum that may accumulate below the porous plate 22 can readily be The means for holding the plate or screen 22 in place may be of any suitable type, such as an eyebolt as at 26, or a spring as at 27. In the eyebolt arrangement as disclosed in Fig.

between the cap and eyebolt, is dismentof the plate 22.

In the eyebolt arrangement disclosed in Fig. 4 a rubber ball or other. suitable material is shown at 28, fastened to the cover or'cap 17 of the saltpot 16, thereby permitting of a certain amount of resiliency to the action of the porous plate 22. r

Leading from the saltpot 16, in Fig. 1 at a point between the upper surface of the and the under surface of the cap 17 of the saltpot is a soft water connection 43 leading through the water. valve 44 and an In Fig. 10, leading from the saltpot 16 at a point preferably from the lower portion.

thereof, is a soft water connection 43, which leads through the water valve 44, and to an outlet line 45.

In the process of regenerating when using the modified form of the apparatus as disclosed in Fig. 10, the valve 15 is opened and valve 12 closed. Valve 10 is opened; this carries the hard water through valve 44 con necting line 43 into the bottom of the saltpot l6, back-wasliing the filter plate 22 and carrying the fines into lines 42, hence into the free-board space 6 of container 1. The light scum, obviously, will remain at the top of the saltpot 16 and may be drawn off through a drain connection 25.

In the process of regeneration as practiced in this invention in Fig. 10, the valves12 and 44 are closed. The valve 10 is opened, from the system. e set screw 19 is loosened and the element 18 removed, a cap 17 removed and the salt added on top of the porous plate 22 in saltpot 16. The cap 17 and the yoke 18 are re' placed and the cap securely sealed by means of the element 19, the valve 44 is opened, which carries the hard water through line,43 into the saltpot 16, thereby dissolving the salt into a brine and carrying it through the element 42 into free-board space 6, down through-the mineral 5, thereby forming the exchange from calcium to sodium in the base exchange mineral, and allowing the hardness to drain out through drain valve '10. When sulficient time and amount of brine solution has passed through the base exchange mineral and drained from valve 10, the valve 10 s closed, valve 44 closed and valve 12 opened. This reverses the current of hard water to the bottom of the softener and by opening line 25of saltpot 16, the flow of water will pass up from container 1, base exchangemineral 5, through free-board space 6 connecting element 42 to saltpot '16 and hence-to drain at point 25. This carries the suspended sediment and removes any remaining salt solution or brine from system when the water passing from 25 registers soft, valve 25 is closed, valve 15 closed and 44 opened. This connects the mains with the soft water and the softener is again in operation.
